Performance/thruput in mixed mode

I finally get to use the FAQ. Neato. Max theoretical speeds: only is 24.4Mbits/sec max. 802.11b/g mixed is 14.4Mbits/sec max.
That's nice. Any particular client model numbers? So what speeds are you getting with each mode?

802.11g only is 24.4Mbits/sec max. I'm not worried about the actual performance - I'm just trying to understand if there is a performance hit in mixed mode networks vs pure g mode. So, will the g mode adapters run slower in a mixed mode network than if they are in a g only network?

802.11g only is 24.4Mbits/sec max. Yes. What happens is that the access point switches between "g" mode and listens for any "b" packets every once in while. If it hears just one "b" packet, it will time slice between "g" and "b", even if there is no "b" traffic (i.e. traffic from the neighbors). The exact amount of time that the access point listens for "b" clients varies by implimentation, but it's substantial (about 40%). While the access point is listening for "b" traffic, all "g" traffic just stops.

802.11g only is 24.4Mbits/sec max. Got it. Thanks!
